Zookeeper access logs?

[rammohan ganapavarapu <ra...@gmail.com>]

Hi,

Does the zookeeper have access logs, i wanted to see client reads and
writes information. Recently we had an incident where some of the clients
started pounding zk with a lot of reads and it was hard to find which
client was doing that.

Partrick,

Thanks for the references, so what loglevel i should be setting to log read
access? I can't rely on connections as the client may be using a pool and
it doesn't translate well with number of reads and writes by a client right?

There is audit capability in newer versions:
https://zookeeper.apache.org/doc/r3.6.1/zookeeperAuditLogs.html

Earlier versions include support for dumping the transaction log (which
goes back a long way):
https://zookeeper.apache.org/doc/r3.6.0/apidocs/zookeeper-server/org/apache/zookeeper/server/LogFormatter.html

For read access you may need to enable logging (log4j) or look at the
connection level metrics.
